Plumbing Questions, Answered

Yes. Lud's Plumbing answers emergency calls 24 hours a day, seven days a week, including nights, weekends, and holidays, across the DMV — Northern Virginia, Maryland and Washington, DC. Emergency calls reach our team rather than a national call center, so we can talk you through shutting off the water while a licensed plumber is dispatched to your address.

Shut off the main water valve to the house immediately, then open the lowest faucet in the home to relieve remaining pressure in the lines. Cut power to any circuit near standing water at the breaker panel. Then call a licensed plumber. Moving quickly on the shut-off is what limits the damage.

In most Woodbridge-area homes it sits where the water line enters the house: a basement wall, crawlspace, garage, or utility closet, often near the water heater. There is also a curb-stop valve in the meter box near the street, which requires a meter key to operate. Find yours before you need it.

Yes. Sewage entering the home is a health hazard as well as a plumbing failure. Stop using all water in the house immediately, since every flush and every drained sink adds to the backup, and keep people and pets away from the affected area. Call for emergency service right away.

Turn off the water supply valve at the top of the tank, then cut the power: flip the breaker for an electric unit, or turn the gas control to off for a gas unit. Do not attempt to drain a hot tank yourself. Call us and describe where the water is coming from.

Response time depends on your location and current traffic on Route 1, Prince William Parkway, and I-95. Woodbridge, Lake Ridge, and Dale City are our fastest addresses at roughly ten minutes. We will give you a realistic arrival window on the call rather than an optimistic one, and we will help you stop the water first.

A conventional tank water heater typically lasts 8 to 12 years in Northern Virginia, and a well-maintained tankless unit lasts 15 to 20. Annual flushing and timely anode rod replacement matter more than brand. If your tank is past ten years and has never been flushed, plan for replacement rather than waiting.

Repair when the tank is under about eight years old and the failed part is a component such as a heating element, thermostat, thermocouple, or gas valve. Replace when water is coming from the tank body itself, when the unit is past ten years, or when repair cost approaches half the price of replacement.

Sediment has settled on the bottom of the tank. Water trapped beneath that layer superheats and forces its way out, producing a popping or rumbling sound. Flushing the tank usually quiets it and restores efficiency. Long-term buildup insulates the burner from the water and shortens the life of the tank.

It can be, especially for households that run out of hot water or want the floor space back. In Virginia, winter groundwater is cold enough that undersized units disappoint, so correct sizing is critical. Install cost is higher because of gas line and venting requirements, while operating savings are real but gradual.

A one to two bathroom home is usually well served by a 40-gallon tank, a three-bathroom home by 50 gallons, and larger households by 75 gallons or a properly sized tankless unit. Recovery rate matters as much as capacity, which is why a gas unit often outperforms a larger electric tank.

A cable, or snake, bores a hole through the clog so water flows again, leaving buildup on the pipe wall. Hydro-jetting uses water at roughly 3,000 to 4,000 PSI to scour grease, scale, and roots off the full pipe diameter. Jetting lasts far longer when clogs keep coming back.

Because the underlying cause was never removed. Repeat clogging usually indicates grease coating the pipe wall, tree roots at a joint, a low spot holding water, or a partial pipe collapse. A camera inspection identifies which one applies, and only the first two are actually solved by cleaning the line.

We advise against them. Caustic cleaners generate heat that can deform PVC, accelerate corrosion in cast iron and galvanized pipe, and rarely clear a full blockage. They also create a hazard for whoever opens the line afterward. Mechanical clearing by cable or jetting is safer and far more effective.

A clog clears when cabled and stays clear. A broken line backs up again quickly, often within weeks, and frequently shows surface signs such as sunken ground, unusually green grass along the run, or sewer odor in the yard. Only a camera inspection distinguishes the two definitively.

In most Prince William County jurisdictions the property owner is responsible for the lateral from the house to the connection at the public main, including the section under the front yard. The utility maintains the main. Confirm with your local service authority before scheduling repair, since responsibility lines vary.

Sometimes. Trenchless methods such as pipe lining and pipe bursting avoid a full-length trench when the existing line has consistent diameter and no severe collapse or offset. Not every line qualifies, and a camera inspection determines it. Where trenchless is not viable, targeted excavation keeps disturbance to a minimum.

Polybutylene is usually dull grey, sometimes blue or black, flexible, and stamped PB2110. Look at the pipe entering the water heater, at the main shut-off, and under sinks. It was installed widely in homes built from the late 1970s through the mid 1990s and is considered a failure-prone material.

PEX installs faster, resists freeze damage better, costs less, and requires far fewer wall openings because it runs continuously between fittings. Copper is rigid, long-proven, and preferred by some homeowners for exposed runs. Both are code-approved in Virginia, and most residential repipes in this area use PEX.

A typical single-family repipe takes two to five working days for the plumbing itself, plus drywall patching and paint afterward. Water is normally restored at the end of each working day, and at least one bathroom stays usable. Multi-story homes with finished basements sit at the longer end of that range.

Pinholes form as corrosion works outward from inside the pipe, driven by water chemistry, high water velocity in undersized piping, or contact between dissimilar metals. One pinhole is a repair. Several within a short period usually means the system has reached the same stage of life throughout and repiping should be priced.

Water expands as it freezes, and pressure builds between the ice plug and a closed fixture until the pipe splits. In Northern Virginia the usual victims are hose bib lines, pipes in exterior walls, and runs in unheated crawlspaces and garages. The split is often not discovered until the thaw.

If the cause is corroded galvanized pipe narrowing internally, then yes, dramatically. If the cause is the buried service line from the meter or a failing pressure-reducing valve, an interior repipe will not help at all. We test before recommending, because those are different jobs with very different costs.

Send us a written quote from a licensed plumber for a qualifying service, along with a photo or PDF of the quote. We review it and come back with a lower offer, typically within 24 hours. The same workmanship warranty applies to price-matched work.

Main sewer line replacement, main water line replacement, whole-house repiping, water heaters, and water filtration systems. The competing quote must be written, itemized, and from a licensed plumber for comparable scope and materials. Verbal estimates and quotes from unlicensed providers cannot be matched.

For planned work such as water heater replacement, repiping, and sewer or water line projects, we provide a written quote before work begins. Diagnostic work such as leak detection or camera inspection involves labor and equipment and is priced accordingly. We tell you exactly what applies before we come out.

After-hours, weekend, and holiday calls carry different rates than scheduled daytime work, which reflects the cost of staffing around the clock. We tell you the rate on the phone before dispatching, and we quote the repair itself before starting work rather than presenting a total afterward.

⚠️ CONFIRM BEFORE LAUNCH — financing options, promotional offers, and an annual maintenance membership are under discussion but not finalized. We do not advertise offers we cannot honor. Call and ask what is currently available, and we will give you a straight answer.

It permits the holder to pull permits and supervise plumbing work. Many companies dispatch technicians; here, the master plumber owns the business.

Our workmanship warranty covers the quality of our installation and repair labor.
